"Outstanding from first meeting & purchase to 24Kw Generac's first start up. Amanda Tallman is completely thorough explaining all installation steps & the numerous items pertaining to this model. On the final day, in the rain, alone Amanda improved the propane line installed by gas supplier. We were so grateful for installation before cold weather & frozen ground occurs. Completely SATISFIED with 4 POWER NOW Roger Sevilla Throop Township."

"I called Green Homes, Home Depot, and Comfort for estimates.  Prices for Green Homes and Home Depot were nearly identical.  Green Homes took more time to explain the features of the windows, show a sample, give considered opinons on options when I requested them, and didn't have extra costs that Home Depot did.  I ended up cancelling the comfort estimate.  I've used them before, and was happy to try someone else. 
They came out right away for the final measurement and gave a tentative date for install.  I called a week or so later, and they confirmed the date, which was only about 3 weeks.  Just after 5 on the Friday before the install I realized I never got a confirmation call, and they were closed so I couldn't call.  But no worries, at about 8:30 Monday morning they pulled in.  Jeff, Jeff, and Mark were great all day.  They did the rooms that I needed done first first, and the room that I  needed last last (moving some furniture around).  They got the inside work on the 12 windows, including trim replacement, done day 1.  Day 2 they arrived again about 8:30 and quickly installed the slider door, then began the outside wrapping.  In the pouring rain.  They're due back for about 1/2 day tomorrow to finish the wrapping outside. 
The windows seem like very good quality.  They missed the grids on 1 window, but the guys knew it and told me as soon as they arrived on day 1.  They installed the wrong window, and will be back out when the correct one is received.
I wouldn't hesitate to call these guys again for service.

"Hired Johnny B Goode to install mini split heat pump to a new construction. Unit is up and running. John had to make a couple trips in order to make this install happen with the other parts of the home construction. He was good about collaborating with the other contractors and at the end all came together nicely. Saved a few hundred dollars going this route. I would recommend Johnny B Goode Heating."

Install Boiler FAQs, answered by experts

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

Most installations take 2-5 days, including old system removal and setup.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.
